Description

A slope reinforcement structure

technical field

The utility model relates to the technical field of slope reinforcement, in particular to a slope reinforcement structure.

Background technique

With the development of my country's national economy, the construction of basic transportation facilities has entered a stage of rapid development. In the mountainous and hilly areas of our country, there will be a large number of slope projects in the construction of roads and railways. In order to ensure the normal operation of transportation facilities, the protection of slope engineering is particularly important. At present, anchor rods (cables), grids, reinforced concrete, etc. are generally used to reinforce the structure. However, these reinforced structures will consume a lot of building materials and have a certain impact on the environment. For example, reinforced concrete reinforced structures need to consume a large amount of reinforced concrete materials during construction, which is labor-intensive and not environmentally friendly.

Existing slope reinforcement methods generally adopt the method of pouring concrete and/or planting green plants for reinforcement. For road or railway slopes with low heights, it is still applicable to reinforce the slope by pouring concrete and green plants. Slope greening treatment is also widely used in highway and railway slopes, and good results have been achieved. In addition, open-pit mining will cause devastating damage to surface vegetation. With the mining of ore, open-pit stope slopes will be formed. The surface of the slope is bare and there is no vegetation growth, which has a great impact on the environment and is easily eroded by rainwater. natural disasters such as landslides. At present, most mining enterprises have not adopted a systematic treatment plan for the slope of the open pit, and few mining enterprises have carried out slope protection treatment such as vegetation greening on the slope of the open pit.

For the open-pit stope slope of mining engineering, its height can reach more than 200 meters. On the one hand, the concrete pouring is inconvenient to construct, on the other hand, the construction period is long, the manpower and material resources are large, and it is not environmentally friendly, so it is not advisable; Slopes are generally high and steep, and it is difficult to gather water and nutrients needed for plant growth on the surface of the slope, and it is difficult for plants to survive. Therefore, new technologies are needed to provide water and nutrients to plants growing on high and steep slopes to promote growth. .

Since the green plants did not take root and survive in the early stage, it is necessary to lay protective nets on the upper and/or lower layers of the vegetation layer. A typical example is a spray-free slope protective net pad disclosed in Chinese patent 201810190098.X, which includes a five-layer structure , from top to bottom are the first mesh layer, diversion layer, vegetation layer, degradable cotton mesh layer, and the second mesh layer. The five-layer structure is fixed into an integrated structure through a number of fastening lines. The first grid layer, the diversion layer and the second grid layer are all made of plastic, which cannot be degraded and is not environmentally friendly. Another Chinese patent 201810745752.9 discloses a plant fiber blanket for ecological protection of road slopes. The upper shaping net is also a one-piece structure. Although its mixed fiber layer, bearing film layer and fiber covering layer are all degradable plant fibers, the upper shaping net and the lower shaping net as the main components of the fixing function are both PP mesh cannot be degraded and is not environmentally friendly. Another Chinese patent 201811203736.3 discloses an ecological slope protection method that is conducive to the growth of slope plants. The scheme proposes to bury non-woven fabrics in the soil at the top of the slope, and then lay grass woven from palm bark on the non-woven fabrics. Grid, and then backfill the garden soil on the grass planting grid, and then sow grass seeds on the garden soil. Although the palm bark woven grid in this scheme can be decomposed, and the non-woven fabric is also relatively easy to degrade, the non-woven fabric and palm The bark weaving grid has great flexibility, and it does not have enough protective force on the garden soil. The garden soil is easy to lose, and it is difficult to ensure the survival of the plants.

The surface of the open pit slope is generally exposed rock, and many micro-cracks are generated inside the slope under the action of blasting mining method. Under the action of rainwater intrusion, cracks are easy to develop, which ultimately affects the overall stability of the slope. A technique is needed to heal the fissure and prevent further growth. Microbial geotechnical technology is currently one of the most innovative technical fields in geotechnical engineering. This technology creatively uses abundant natural non-toxic microbial resources to modify the microcosmic structure and composition of rock and soil, thereby improving its engineering mechanical properties, including strength, stiffness and permeability etc. Microbial geotechnical technology can be applied to many fields such as rock and soil reinforcement, seepage prevention and plugging of dams and structures in the soil, sand and soil liquefaction prevention, and concrete crack repair.

At present, the microbial geotechnical engineering technology is mainly MICP (microbial induced carbonate precipitation), which is the microbial induced calcium carbonate crystallization technology. The free calcium ions react to form gelled calcium carbonate precipitates. Gelled sedimentation can not only fill pores, but also bond sand particles, thereby improving the mechanical properties of rock and soil. For example, Chinese patent 201710815243.4 discloses a microbial reinforcement method for accumulation slopes, but this scheme proposes to use the sedimentation of microorganisms to reinforce the slope, but in the later stage of the scheme, it is necessary to inject concrete mortar into the injection pipe of the microbial nutrient solution mixture The operation, one is troublesome to operate, and the other is that the concrete cannot be degraded and is not environmentally friendly.

Therefore, there is a need in the prior art for a solution that is environmentally friendly, capable of providing sufficient protection to the planting soil, and is easy to operate to solve these problems.

Main implementation process and principle of the present utility model are roughly as follows:

1. Lay a well-shaped protective pipe network on the slope surface of the open-pit mine that has been closed. The inner diameter of the wooden conveying pipe (that is, the plant fiber pipe) is about 5mm and the outer diameter is about 10mm. In the early stage, the pipe is mainly responsible for transporting the mixed solution of microorganisms and nutrient solution, and in the later stage, it is mainly responsible for transporting the water and nutrient solution required by plants. The wooden delivery pipe is in the soil for a long time, it will slowly corrode and decompose and transform into nutrients such as inorganic salts needed by plants, which will be reabsorbed by plants, which is more environmentally friendly than traditional PVC plastic pipes. The pipes are staggered to form a grid-shaped well-shaped transportation pipe network (ie, a protective pipe network). One or two delivery ports are reserved on the liquid supply pipe at the top of the slope, and the liquid is mainly transported through the delivery ports. Drill a circle of drain holes at a certain distance, such as 5-10cm, on the horizontal conveying pipe, so that various liquids can flow out of the conveying pipe to reach the slope surface smoothly. Of course, the length of each transverse conveying pipe and longitudinal conveying pipe can be appropriately set according to the height of the slope. For example, the length of a single pipe can be 2 to 3 meters, which is convenient for transportation. If the slope surface is undulating, it can be set shorter. A connecting elbow of degradable material can be provided at the ups and downs. The purpose is to enable the pipeline to be laid according to the ups and downs of the slope surface, and to better adapt to the specific ups and downs of the slope surface. Because the conveying pipe is compiled into a mesh-shaped well-shaped conveying system and fixed on the slope surface with wooden piles, it can strengthen the slope to a certain extent, improve the stability of the slope, prevent the gravel from falling on the surface of the slope, and prevent people from mining and the machine is harmed.

2. After the wooden well-shaped delivery pipe network is laid on the slope surface, the mixed solution of microorganisms and nutrient solution will be delivered from the top of the slope through the liquid supply pipe, and the mixed solution will reach every part of the slope through the delivery pipe, and then pass through The discharge hole of the delivery pipe reaches the slope surface. Because there are many cracks and joints on the surface of the slope, the mixed solution flows into the deeper slope through the cracks and joints, and the delivery of the mixed solution is stopped after the cracks and joints on the slope surface are filled with the mixed solution. Microbial mineralization automatically heals the cracks and strengthens the slope. Provide nutrients such as urea and calcium salt solution to specific microorganisms through wooden delivery pipes, use the catalysis of urease produced by microorganisms to decompose nutrients to produce carbonate ions, and combine with calcium ions in the surrounding environment to form calcium carbonate crystals, gradually Solidify and bond the cracks, so as to achieve the automatic healing of the cracks on the slope surface, and enhance the strength and integrity of the rock mass of the slope, and finally improve the stability of the slope.

3. After stopping filling the cracks on the slope surface with the mixture, spread the mixed soil containing the nutrients and plant seeds needed for plant growth on the slope surface with a thickness of 2-3cm and be able to bury the laid wood delivery tube. The plant seeds should be selected according to the conditions of the rock mass of the slope, for example: lymus seeds, magnolia seeds, cosmos seeds, tall fescue seeds, ryegrass seeds, etc. The plants are all fast-growing varieties, which can ensure that they can grow to fix the side slope before the wooden pipe is corroded. Faster-growing varieties require more nutrients, so it is of great benefit to provide water and nutrients from the roots. It can ensure the survival and rapid growth of plants.

4. After the plant seeds and the soil required for their growth are laid on the slope surface, a small amount of water is transported to the mixed soil through the wooden delivery pipe laid in the previous stage, so as to avoid a large amount of water forming a flow and taking away the laid soil. When the plant encounters dry weather and lack of water during the whole growth process of the plant, the root system of the plant can be provided with water through the delivery pipe. The method is simple and convenient to operate, and can avoid spraying the plants from above the plants (because it is difficult to spray water on the slope); providing water from the roots of the plants can save water to a large extent; providing water to the plants through pipes Moisture, the amount of water to be watered can be monitored through the water meter, and the water can be scientifically provided to the plants, which is beneficial to the growth of the plants. Planting plants on the slope, especially plants with well-developed root systems, can improve the shear resistance of rock and soil, improve the integrity of broken rock and soil, and improve the strength of rock and soil; the presence of plants can prevent rainwater from infiltrating into deep parts during heavy rain seasons In the rock-soil mass, it affects the integrity of the rock-soil mass and can effectively prevent the occurrence of landslides.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
